RTA 460ETCDHM Alternative: EtherNet/IP to Data Highway Plus (DH+) Gateway
If you are searching for a reliable RTA 460ETCDHM alternative, the Real Time Automation (RTA) gateway is commonly evaluated to bridge Ethernet-based Rockwell Automation ControlLogix or CompactLogix PLCs with legacy Data Highway Plus (DH+) devices, such as PLC-5 and SLC 5/04 processors. With competitor gateways listing upwards of $1,495–$1,510 USD and requiring complex tag-mapping tables, automation maintenance teams need a simpler, transparent drop-in solution.
The ANC-100e delivers full drop-in replacement functionality, providing direct, transparent EtherNet/IP-to-DH+ connectivity without the overhead of building and maintaining hundreds of tag mappings.
Why the ANC-100e is the Ultimate RTA 460ETCDHM Replacement
Unlike traditional mapping gateways that require manually configuring input/output scan lines and registers, the ANC-100e utilizes standard ControlLogix Ethernet routing drivers natively supported by RSLinx Classic, FactoryTalk, and modern SCADA platforms:
- No Tag Mapping Overhead: Direct access to DH+ PLC-5 and SLC 5/04 data tables without configuring hundreds of Logix tag-to-register schedules.
- Automatic DH+ Baud Rate Detection: Automatically senses 57.6 kbps, 115.2 kbps, and 230.4 kbps DH+ networks without manual DIP switch adjustments.
- Auto-Polarity & Node Assignment: Automatically adjusts to network wiring polarity (Blue/Clear reversal protection) and assigns a free DH+ node address on the network.
- Modern SCADA & HMI Integration: Direct communication for Ignition SCADA, Kepware, AVEVA Wonderware, FactoryTalk View, and PanelView Plus 6/7.
- Full RSLogix Programming Support: Enables online monitoring, upload, and download in RSLogix 5 and RSLogix 500 via standard Ethernet drivers.
- Compact & Cost-Effective: Ultra-compact form factor priced at $1,195 USD, saving hundreds over RTA and ProSoft alternatives.

Transparent Bridge vs. Tag-Mapping Gateway
The primary difference between the ANC-100e and the RTA 460ETCDHM lies in application architecture. The RTA gateway acts as an intermediary data broker, requiring engineers to define PLC data file locations (such as N7:200 or F8:0) and map them to Logix tags.
In contrast, the ANC-100e acts as a transparent network bridge. Ethernet software connects directly to the DH+ network using standard ControlLogix routing, allowing plant engineers to keep their existing PLC-5 and SLC 5/04 hardware without rebuilding communication logic.
